JAMES L. HAVEN AN D' CHARLES HETTRIGK OF CINCINNATL OHIO. Letters Patent No, 59,745, dated November 20, 1866.

TO ALL WHOMl IT MAY CONOERN;

Be it known that we, JAMES L. HAvnN and CHARLES HETTRICK, both of Cincinnati, Hamilton county, Ohio, have linvented a new and useful bandelore, and we do hereby declare the following to be a full, clear, and exacj description thereof, reference being` had to the accompanying drawings making part of this specification.

lp Our invention is an improved construction of the toy, commonly called a bandelore, and consists Vin forming the same of two disks of metal, coupled together at their centers by means of a clutch and rivet in the manne] following.

Fig. 1 is a. perspective view of a bandelore embodying our improvements. Fig. 2 is an'axial section through the same. Y Fig. 3 is an inner side view of one of the component disks. A, B, represent two similar circular plates or disks, having on their outer sides a. marginali-im or swell C and having a central aperture D, surrounded on the inner side of each disk by an indented annular boss E, th indentations of one boss being adapted to receive'the projections of the other boss, so as to interlock iirml: together on the principle 'of a clutch on the insertion and clenching of a rivet F. i

. Une or both disks are provided `iust outside .of the boss with a small hole G, to secure the string H, b; which the instrument is operated.

By means of the above construction we are enabled to make the bandelore of metal, and thus secure in 1 `high degree the momentum which is essential to easy operation of the toy.

It will be observed that the marginal swell C, exercises the function of a {1y-wheel. We have selected for illustration the yform actually manufactured by us, but the device is susceptible c r various modiiications-for example, the web or central portion may be of ornamental open work and variou devices may be employed in they conformation of' both the web and the exterior rim, and the rivet may be re placed by a screw. i

We claim herein as new and of our invention- The disks A, B, united at their centres by the rivet F, and interlocking bosses E, substantially as set forti JAMES L. HAVEN,

CHARLES HETTRICK.
